Answer
Explanation:
Step1: Calculate Erika's average time
Sum of Erika's times: $20 + 21.5+22.75 + 23.25+20.25=107.75$. Average time $=\frac{107.75}{5}=21.55$ minutes.
Step2: Calculate Rita's average time
Sum of Rita's times: $21.25+24.75 + 23+23+20.75 = 112.75$. Average time $=\frac{112.75}{5}=22.55$ minutes.
Step3: Find the difference
Difference $=22.55 - 21.55 = 1$ minute.
